Great article TinGoat! Don't know much about electricity, but what the hell--I'll risk being blown up to get a resistance soldering rig. Actually, with three sons of varying talents and utility (for my purposes) I'll tag No. 3--the real life electrician--for this build. Thanks TinGoat.

I have a resistance soldering rig but don't use it for most of my small scale( N or TT) track soldering. I find it easier to use a small pencil iron, the resistance rig requires one to keep track of and push the foot pedal while the pencil iron is always on and is also lighter and easier to handle than the resistance tweezers or probe. I used the resistance rig more when building O scale track as the larger rail sections needed more heat. For TT scale a heat controlled unit like a weller WesD51 or Hakko fx888D might be more useful......DaveB
